Code Behind File, variables not found.

I'm trying to put all the coding in my various pages into the code behind file...
I'm also using a Master page.

This is what I have at the top of my .aspx file:

<%@ Page MasterPageFile="master.Master" AutoEventWireup="false" CodeBehind="search.aspx.vb" Inherits="search" Src="search.aspx.vb" %>
This is how what I have in my aspx.vb file:

Partial Public Class search

    Inherits Page


Visual Studio 2005 doesn't show any errors, but when I view in the browser I get...
Compiler Error Message: BC30451: Name 'fieldOfSearchDropDownList' is not declared.
fieldOfSearchDropDownList is definately declared.
